AXI-Pack: Near-Memory Bus Packing for Bandwidth-Efficient Irregular Workloads
Abstract
AXI-Pack is proposed as an extension to the ARM AXI4 protocol designed to address the bandwidth inefficiencies of irregular memory streams (strided and indirect accesses) in on-chip interconnects. This extension introduces specialized
